This study investigates morphological alterations in patients with left temporal lobe epilepsy (TLE) due to ipsilateral antero-inferior temporal lobe meningoencephalocele (TLM). Compared with healthy control (HC)s, cortical thickness was increased extensively in both cerebral hemispheres with reduction in a few regions, most remarkably in the left temporal lobe. Both amygdala were significantly bigger in the patients compared with HCs. No difference was found in hippocampi and thalami between patients and HCs or between hemispheres within the patient group. No relation was found between these significant alterations and duration of disease.
